BRACE CONSTRUCTION.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed October 3, 1918. Serial at; 256,646;

To a whom. it 122 (13 concern:

Be it known that I, WALTER I. TUTTLn, a citizen of the United States,and a resident of Providence, in the county of Providence and State ofRhode Island, have invented an Improvement in Brace Construction, ofwhich the following is a specification.

This invention relates to the construction of braces and the like, andmore particularly to the end 'or thrust handles thereof. One of theobjects thereof is to provide a construction of the above type ofefficient action and stron dependable structure. Another object is toprovide a construction of the above type which shall be light in weightand cheap in manufacture. Other objects will be in part obvious and inpart pointed out hereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangements of parts which will beexemplified in the structurd hereinafter described and the scope of theapplication of which will be indicated in the following claim.

In the accompanying drawing in which is shown one or more variouspossible embodiments of this invention,

Figure l is a side elevation cut away through the handle; and

Fig. 2 is a vertical section through the handle portion thereof, on anenlarged scale.

Similar reference characters refer to similar parts throughout theseveral views of the drawing.

Referring now to Fig. 1 of the drawing, there is shown a brace havingcrank portion 1 with end portions or members 2 and 3. It is to beunderstood that these end members may be formed integral or separatefrom the intermediate portions of the brace, and that the term endmember is used broadly throughout.

Secured to end member 2 is the device which is operated by the brace,here shown as a socket member 4: to form a socket that a chuck might beemployed at this point and many of the advantages of the inventionachieved.

Referring now more particularly to the opposite end of the brace,especially as shown in Fig. 2 of the drawing, there is provided at theextremeend of the member 3 a beveledshoulder 5 which may be formedwrench. It is clear, however,

by upsetting the metal. This shoulder fits within the correspondingrecess or countersink 6 in a sheet metal member '7. The lat-- ter memberis provided with a sleeve portion 8 embracing the member 3 and forming abearing therewith. The member 7 is also provided with an outwardlydirected curved fiange9 as shown inthe drawing.

Fitted about the above parts is a member 10 also preferably formed ofsheet metal and spun substantially into the shape indicated. This memberconforms to and covers the outer extreme end of the member 3, and flange9 of the member 7, and is thence curved along the brace and finallyinwardly as indicated at 11. The edge of the member is preferablybeveled as at 12 so as to avoidpresenting a sharp edge to the fingers.

"When the parts are assembled, the member 7, with the contained shank orend member of the brace, is secured, preferably by welding or riveting,at at 9*, to the inner surface of the outer member 10 as indicated inthe drawing. i

The above construction forms what is termed the thrust handle asdistinguished from a possible handle on the crank of the brace, and itis to be understood that this term thrust handle is broadly usedthroughout.

In the action of the device, the end member of the brace is securelylocked into the handle and yet turns therein with perfect freedom. Norotating parts however are exposed to the hand of the user and thus anydesired degree of pressure may be exerted without discomfort. The entiredevice is of light construction and correspondingly economical in metal,and is of low cost of manufacture. Its durability as well as conveniencein use will be obvious.

It will thus be seen that there is vprovided a construction in which theobjects of this invention and the above-noted as well as otheradvantages, gained.

As various possible embodiments might be In brace construction, a.swiveled handle comprising in combination a hollow metal handle member,a bearing member having a sleeve or bearing portion and an outwardlyextending 'flange, and fitting and resting with its end surface againstthe inner surface of said handle member adjacent itsfcen- .tral portionand secured thereto, said flange flarin outwardly from the sleeveportion to provi e a-circular recessadjacent said handle member, and ashank member having a bearing in said sleeve portion and an end 10bearing against said handle member, and extending outwardly between saidhandle member and bearing member into said recess to lock-itself inposition. v

Intestimony whereof, I have signed my 15 name. to thisspecification this17th.day of September, 1918.

WALTER I. TUTTLE.
